Make sure the seams are on the outside of the vertical guides in the slicer before printing.

Model Description

This Corner Radius Template Set is a compact woodworking aid designed to quickly and accurately mark rounded corners on planks, boards, and panels.

The set includes six nested radius templates with radii of 5, 10, 15, 20, 25, and 30 mm, covering the most commonly used corner sizes in furniture and general woodworking. Each template is shaped to sit squarely on the corner of a work piece, allowing you to trace smooth, consistent curves with a pencil or marking knife.

All six templates nest neatly into one another and are designed to be kept together using a carabiner, making the set easy to store, transport, and grab in the workshop. The compact stacked design prevents lost pieces and keeps all radii organized in one place. The large holes in all piece line up when stacked together so something can be used through all the holes when stacked to keep them together. I used the carabiner from original designer @WalterHsiao and re-posted by SMT_M here on Creality Cloud. It can be found here:

Perfect for cabinet making, furniture projects, trim work, and DIY builds

Design Concept

The goal of this design was to create a simple, durable, and space-efficient corner radius marking tool tailored for everyday woodworking use.

Instead of loose individual templates, the radii are designed to stack and nest, forming a single compact unit. This not only saves space but also ensures that every radius size is always available when needed. A dedicated hole allows the entire set to be secured with a carabiner, keeping the templates together and easy to hang in the shop or attach to a tool bag.

Each stencil features:

-A flat reference edge for accurate alignment on plank corners

-A smooth radius profile for clean, repeatable marking

-Clear radius identification engraved on the surface

The result is a practical workshop accessory that improves speed, consistency, and organization while remaining simple enough to 3D print and customize.

Printing suggestions

- 3 walls for a bit more strength

- Make sure the seams are on the outside of the vertical guides.
